trunks, muscles, back, or head of a patient, and retain it there for some time, regardless of the condition of variation, of den- sity of current, or of interruption, direction, or alternation, &c, would be a foolhardy and highly hazardous experiment. In my opinion no such current should ever traverse the part more than one minute at a time, at the longest, although repeated again and again in the same place and manner. See D, Note 3. The Faradaizing of the diaphragm for quickly producing arti- ficial respiration is, according to Duchenne, best done by apply- ing the one electrode over the phrenic nerve, which takes its rise from the third, fourth, and fifth cervical pairs, and is to be reached on the anterior edge of the scalenus anticus, and just at the back edge of the middle of the sterno-cleido-mastoideus mus- cle, while the other electrode is placed at the pit of the stomach, with a down-running current. Let the electrodes be wet sponges with large surface. The instant they are applied, the artificial respiration is usually produced; the thorax heaves, and the air rushes forcibly into the lungs ; thus by applying and removing one electrode as often as this phenomenon is repeated, it is possible to keep up a respiratory process for a time, even after death. Perseverance must be the motto here; for in all cases of apparent death from water, strangulation, lightning, asphyxia, from chloroform,, opium, carbonic acid gas, <fec, to establish and maintain respiration, is often found to save life. For the Faradaization of the pharynx, he uses the long han- dle electrode with " olive-shaped tip," which is to be introduced into the pharynx in median line, while the other wet electrode is placed on the nape of the neck. He cautions against the acci- dent of allowing the excitors to touch or rest against the lateral sides of the pharynx, for the pneumogastric, glosso-pharyngeal, and spinal accessory nerves might be touched by the current, and thus affect the vital organs. The Faradaization of the larynx is done by means of the same olive-shaped instrument, which is passed down (without the current) as far as the posterior and inferior portion of the larynx, while the other excitor, as in the previous cases, is then placed on the nape of the neck; or it is better sometimes to be 29
